LUBRICATING DEVICE.

Specification of Letters Patent. i

Patented Feb. 25, 1908e- Application filed June 22| 1965. Serial No. 266.882.

To all whom it may concern.'

Be it known that I, VALTER SCOTT, a citizen of the United States of America, and a resident of Plainfield, Union county, New Jersey, have invented certain new and useful Improvements in Lubricating Devices, of which the following is a specification.

The present invention relates generally to lubricating devices, and has more 'particularly reference to means for lubricatin the reversing roll spindle of a bedand cyllnder printingmachine. The problem of properly lubricating this reversing roll spindle is a most important one as will be understood from the following: A machine of the character described is usually provided with a rotating impression cylinder, a reciprocating bed having an upper and a lower rack and a gear adapted to alternately engage with the two racks to impart the proper reciprocation to the bed. Suitable means as end slots on the bed and a roll moving the gear are also provided for reversing the motion of the vbed at the end of the stroke in either 'direction.

This reciprocating bed which is very heavy makes a number of .reciprocations' per minute; in fact, in the hi hly developed types the speed is considerab e. Owing to the impossibility of adjusting the pressure of the air cushions which aid in retardingthe motion of the bed at each end to a nicety, considerable strain is frequently placed upon this reversing roll as it practically receivesall the thrust of the bed on the reversal. It will therefore readily be seen that abundant lubrication is necessary upon the spindle carrying this reversing roll. Adding to these considerations the fact that these parts are located under the machine where it is difficult to reach them by hand for the purpose of lubrication, and where there is little available space owing to the proximity of the working parts, it will at once be clear that suitable means for prop-` may of course be made without departing 4. Fig. 4 is a view in elevation of the duct shown in Fig. 3. Fig. 5 is 'a detail sectional viewon the line 5 5 of Fig. 3. Fig. 6-is a plan view, similar to F 2, but showing a modiiication. Fig. 7 is'a view looking in the direction of the arrow 7 in Fig. 6.

Similar numerals of reference indicate cor responding parts in the different views.v

l indicates the reciprocating bed of the` machine having an upper and a lower rack 2 and 3 and provided with suitable end slots as 4 (only one of which is seen) or other suitable means as shoesin a well known'mannenI at the end and intermediate the two racks.

Adapted to engage alternately with the said racks is the rotatable gear 5 whose axis is fixed except fora slight up 4and down movement, in the present instance, to engage and disengage with the racks of the bed in a well known manner. spindle 6 carrying a friction roll-7 adapted to engage in the slot 4b v bearing against the shoes forming the said slots or other equivalent mechanism which may be carried by the bed for coperating with the said roll to re' verse the motion of the bed. In the present instance there is shown a pivoted shoe 8 which is adapted to be moved in by means of the cam 9 after the friction roll has moved in behind it. These parts are all so well known and are only shown and referred to herein order that the difficulties of lubrication may be appreciated and in order to give a clear understanding of how my invention is applied. out and in and roll 7 moves in a peculiar path,

indicated by cc, with relation to therecipro;

Moving with this gear is a inasmuch as these shoes' 8 move eating' bed, hit is very dil'licult to properly lubricate the spindle especially from that side of the gear on which the spindle andv friction roll are located. lt is therefore proposed to locate a source of supply of lubricant 10 on that side of the gear opposite to that on which the spindle and friction roll are located and to make the location of this source. of

.11 for receiving the oil or other lubricant having a channel 12 through which extends the wick or other material 13 for properly I drawing the lubricant out of the same.

Mounted upon the same shaft 14 on which the gear is carried, or mounted upon the ear direct as the case may be, is an arm 1.5 w 'ch Isup orts the spindle 6 having .a suitable duct 17 eading 'from its interior toits surface.

This duct is connected to the duct 18 in they arm 15 and with this duct 18in the arm 15 is connected a duct 19 which extends through the gear and terminates at its outer end in an enlarged portion 20 having a plug 21 which partially closes its outer end so as to preventthe oil from flowing out in case the machine should be stopped ata point Where the duct 19 will be with its open end in a downward osition. This plug is provided with a flaring mouth 22 having an inwardly extending lip 23 and an outwardly projecting ton e 24 which comes opposite to the Wick or ot er material and wipes the o-il off the same and allows it to flow in through the mouth and lip into the enlarged portion20 of the duct 19. From thence it `1s transmitted through the various ducts to the surface of the spindle carryingthe friction roll. The fact that the duct 19 and its auxiliary members move with the gear has the effect of forcing the oil from the tongue into the enlarged portion of the said duct by reason of the centrifugal force caused by the rotation of the gear.

In Figs. 6 and 7 the construction is substantially the same with this exception; that instead of the gear 26 moving up and down, it slides sidewise upon the shaft 27 into and out of enga ement with the two racks 28 and 29 vin a wel known manner. The arm 30, however, which carries the spindle 31 Afor supporting the friction roll 32 is fixed on the shaft carrying the gear and does not slide with it and is therefore spaced a fixed distance from the source of supply 33. In this -instance the duct 34 will be made sufficiently long to extend from the source of su ply to the arm carrying the spindle and t e gear slides over the said duct as it moves into and out of enga ement between the two racks."

necting lwith the interior of the spindle, and 2g'llubricant to the duct, t

means for suppl e said gear.

2. In a printing machine, the combination of a gear for imparting motion to the bed, a spindle for supporting a friction roll located on one side of the said gear and having a duct extending from its interior to its outside sur- Y face, an arm mounted onthe same shaft as the gear and having a duct connecting with the interior of thespindle, 'a duct extending through the said. gear Aand connecting with. the duct in the arm, and means for supplying lubricant to. the duct extending through the said gear.

3. The combination of a rotatable gear, av

spindle .moving with the said gear and located on one side of the same for sup orting a friction roll and provided with a uct connecting its interior with its surface, a source of supply of lubricant whose position is fixed, a duct, having an enlarged portion, extending through the said gear and connecting with the interior of the s indle, a plug closing the outer end of the enlp arged portion of the. duct to prevent the lubricant'from iiowing- :out and-having a mouth provided with an inwardly projecting lip, and an outwardly' i projecting tongue in saldmouth for receiving the-lubricant from the source of supply and allowing it to flow through the mouth and lip into the enlarged portion of the duct.

4. In a printing machine, the combination I of a source of supply of lubricant located in a fixed position, a spindle, for supporting a friction' roll having a duct from its interior to its outer surface, a rotatable gear interposed between 'the spindle and source of supply and having also asliding motion toward vand away from the spindle but rotating in unison with the latter, and -a duct adapted to receive lubricant from' the source of supply vand conveying it to the interior of the spindle on which duct the said gear slides.

5. As a means for transferringlubricant',

a rotating duct having an enlarged portion,

a plug closing the outer end of the enlarged portion to prevent the lubricant from fiowing out and having a Haring mouth provided'v 4with an inward y lwardly projecting tongue ,in said mouth for projecting lip, and an outreceiving the lubricant from a source of supply and allowing it to flow through the mouth and lip into the enlar ed portion of the duct.
